Converting Photocurrent to Voltage
Note:
1. The output voltage (Vout) is the product of photocurrent (IPH) and loading resistor (RL)
2. A right loading resistor shall be chosen to meet the requirement of maximum ambient light,
and output saturation voltage:
Vout(max.) = Iout(max.) × RL ≦ Vout(saturation)=Vcc-0.4V
